McCartney joined Springsteen and the E Street Band to play Beatles classics I Saw Her Standing There and Twist and Shout – but the main PA was switched off part way through the latter song.

Promoter Live Nation issued a statement saying: "It was unfortunate that the three hour-plus performance by Bruce Springsteen was stopped right at the very end but the curfew is laid down by the authorities in the interest of the public's health and safety."

Should Live Nation have risked a fine and other reprecussions in order to let the stars finish their set?
